Mark at digitizationblog is writing a book entitled Putting Content Online: A Practical Guide for Libraries. It will be published in about a year from now. His blog posting talks about his intent to make it practical and not just about digitized materials. Sounds like a book that many libraries and cultural heritage organizations will be able to use, especially those smaller one that have really thought about this yet.
Mark, good luck! We look forward to the formal announcement saying that it's available.
